Optimizing APM in the Cloud: A Retrospective Approach for Future Success

The growth and maturity of the cloud has required us, as tech pros, to manage an increasingly complex web of applications spanning on-premises, hybrid, and multi-cloud environments. While this affords us greater flexibility, agility, and scalability day-to-day, these changes to how we deliver applications are making traditional monitoring techniques much more difficult (sometimes impossible), while […]

Monitoring PHP Performance and Diagnosing Bottlenecks

Last week, we took a quick look at PHP-FPM, reducing process manager (PM) overhead and maxing out PHP-FPM’s throughput by attempting to keep processes in-memory using pm.static. However, beyond development server benchmarks, on our production servers, we also want to drill down into all services and components called up by each user’s interaction. This allows us the opportunity to diagnose PHP and other […]
